5 Formation

5.1 Formation

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Diabase vs Pyroxenite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Diabase and Pyroxenite Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Diabase vs Pyroxenite information and Diabase vs Pyroxenite characteristics in the upcoming sections.
